Abstract
Disclosed is an apparatus that transfers liquefied gas electrolyte (LGE) to electrochemical cells without the need for a temperature differential and without inducing an LGE phase change. The LGE comprises a liquefied gas solvent having a vapor pressure above 100 kPa at a temperature of 293.15 K and a salt. The apparatus utilizes a constant pressure cylinder to transfer LGE entirely in the liquid phase to an electrochemical cell.
Claims20
An apparatus for dispensing a liquefied gas electrolyte (LGE) into an electrochemical cell, comprising:
- a compressed gas source;
- a constant pressure cylinder (CPC) comprising a cylinder body, a pneumatic cavity, a piston, and a product cavity configured to contain the LGE;
- a pressure regulator fluidly connecting the compressed gas source to the pneumatic cavity, the pressure regulator configured to pressurize the pneumatic cavity to a pressure greater than a vapor pressure of the LGE, thereby maintaining the LGE entirely in a liquid phase within the product cavity;
- and
- tubing fluidly connecting the product cavity to the electrochemical cell.
